Wireguard errors (inconsistent)

[yochaigal]

Hello!

I've been using VPN Client for years with OpenVPN on my Pixel 7. Recently I switched over to Wireguard (connecting to a Ubiquiti UXG Lite firewall). It works just fine most of the time, but I experience the following behavior at random times:

• I'm at home, using home wifi (no VPN is in use)

• I go somewhere else (VPN connects to mobile network, works fine)

• I arrive at my destination (VPN disconnects from mobile network, VPN connects to wifi, stops working)

• I turn VPN off and on again (VPN works)

This happens at many different places, and I think even happens on mobile occasionally. The Log shows "write link error: Network is unreachable" over and over again until I turn the VPN off.

This never happened using my OpenVPN connection! Unfortunately it is unpredictable; I can't quite figure out what situation is triggering this behavior.

Here is my log:
